1. Deafult profile image for posting to Creator Community Page should change to the one provided, as it is for the rest of the website
2. On the Manage Channel Page, when creating a new collection, Users should be able to choose in which order the items appear. Currently they are sorted by date of upload, this ought to be changed so that it's the one which user presses that appears first, etc
3. On the Manage Channel Page, when creating a new collection, Users should have to choose a name and thumbnail for the collection. Functionality for adding name already exists, functionality for choosing a thumbnail will have to be added. You will need to make it so user has to select a name to proceed, or else an error message should be displayed. Once name has been selected, user should be taken to another screen showing the items they selected on the previous screen. This would be for selecting thumbnail. User should have to select thumbnail, if not, error message should appear. If user selects thumbnail and confirms, collection should be made. All this should also be applied to the "Favoritemade collection from other creator" interface further down on the screen.
4. On the Manage Channel Page, pressing a collection should bring up an edit screen for it. On this edit screen, user should be able to edit which items are in the collection, what order they appear in, as well as the name and thumbnail. Same should apply for the "Favoritemade collection from other creator" interface further down on the screen.
5. On pages which display content in the gallery, related content, same author, and featured by the author is displayed on right hand side. If an item is in a collection, another section should be added on top of these displaying all other items in the collection in order. The name displayed above the section should be the same as the name of the collection [Collection Name].
